To all whom it may concern.-

Be it'known that WB,-SA1VIUEL- P. Rum and JAMES TIMMS, residents ofColumbu in the county of Franklin and 'State; of Ohio,- have. inventedcertain new and usefuljlmprove ments in Automatic Car-Couplings; andwedo hereby declare the following to bea full, .ol ear-,v

and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the-same.

Our invention relatestoan improvement-in couplings, the object of theinvention being to providefan improvedcouplingin'which the I lockingdevice is'moved from below by a lever or arm to move the locking deviceinto a lock-s'et position or to throw the knuckle open;

'. andthe invention consists in'certain novel features of constructionand combinations and arrangements of parts, as willbe more fullyhereinafter described, and pointedout in the claims. Q

In the accompanying drawings, Figure 1 is a viewt-in' verticalcross-section of the coup ling, showing the parts in locked 'PQSltlOILFig. 2'is asiniilar' view with the parts in lookset position. 'Fig. '3is a view in horizontal section with knuckle removed, and Fig. 4 is anenlarged view of the locking-block. "'1 represents thecoupling-headinwhich the kuucklefis pivoted, and saidknuckle. is

made with a tail 2 at its inner end, having an] inclined o'r beveledlower face, the head being made with 'an oflset or pocket 3 to receive'the end of the knuckle-tail. The knuckle is locked initsclosed positionby a lockingblock 4, having a vrectan'gular.p'ortion to fit between afiat face of theknuckle-tai'land the wall 5 of the head, and the lowerportion of the block is recessed, "as shown at 6, to per: mit theknuckle-tail tofreely pass the block when the latter is elevated. Theupper per;

tion of the block is recessed at one side, forming a lip 7 to' engageover a hook 811 the head 1 and hold the-block in lock-set position.

The block being' top-heavy, when elevated tilts to one side to. theposition showuin Fig.-

head, preventing the lower end of the block 5 from swinging to one sideand compelling the upper end of the block to tilt over and engage thehook., 1

At one side of head 1. a lever9of the'general shape shown islfulcrumedbetween its ends on a pin 10, secured in a pair of lugs, 11,

integral with the head. The upper end of this lever 9fextends partlyoverhead 1 and has. an eye therei-njto receive the ordinaryoperating-chainconnected with a crank-shaft and used'to open thecoupling in uncoupling lip '14, adapted when raised to' a predeterminedheight to engage the lower inclined face of the knuckle-tail, and acontinued up- 7 ward movement ofthe lower ,end of lever 12 will, due tothe cam action, force the knuckle I open. Instead of having this lip-14eon the enlargementlQit might be on the lockingblock." the operationbeing The operation ofour improvements is as follows: When the parts arethe position shown in Fig. 1, the knuckle iseffe ctually locked'in itsclosed position. pull on the ripper 'end of lever 9 serves to .raise thelower end312 thereof and elevatelocking-block 4, and as the latter-israised out of itslocking position owing to its'to p-heavy constructionand the contact of finger 15 with 5 tthe' guide wall in thehead theupper end of the block will tilt over and engage over hook .,8,holdi'ngthe block in fljockjset position, as -shown in Fig 2. 'Should the kn eerh eaee swung open, it'will first dislodge. v 1 e 'block 4 from hook 8and supportthesame'on the knuckle-tail, and when the knuckle is closedthe block will'drop' from'the tail and fall into its locking position.With the parts as shown "in Fig. 2'should theenlarged end 9 5 12 bemoved upwardjitslip 14; will engage the inclined face of 'the knu'ckletail and force the knuckle open. When the lever 9 is" i ejust thesame asAn outward i a locking-block, of an operating device mov-- leased, itsheavier lower end will compel it to assume its normal position. (Shownin Fig. 1.)

To reduce friction and render the operation easy, a ball or roller 16 islocated in-a recess in thecontacting face of lip 14, and this ball orroller engages the knuckle-tail and reduces the friction of the. lipthereagainst as. the knuckle is forced open by the upward movement ofthe lever end.

A great many slight changes might be made in the general form andarrangement of the parts described without departing from our invention,and hence we do not restrict ourselves to the precise details set forth,but consider ourselves at liberty to .make such slight changes andalterations as fairly fall Within the spirit andscope of our invention.

Having fully described our invention, what we claim as new, and desireto secure by Letters Patent, is-- 1. The combination with acoupling-head having an opening in its bottom, a knuckle and ablevertically through the opening in the bottom of the head and operatingto raise the locking-block and cooperating with the tail of. the,knuckle to throw the latter open.

2. The combination with. a coupling-head having an opening in itsbottom, a knuckle havmg a tail provided with an inclined lower face,

and a locking-block, of an operating devicemovable vertically throughthe opening in the bottom of the draw-head to raise the lockingblock,said operating device having a part cooperating with the inclined. faceof the tail of the knuckle to throw the latter open by cam action whensaid operating device is raised.

4 3. The combination with a coupling-head having an opening in itsbottom, a knuckle having a tail provided with an inclined lower face, ofan operating device movable vertically through the opening in the'bottom of the coupling-head and having a part cooperating by cam actionwith the inclined face of the tail of the knuckle to throw the knuckleopen when said operating device is raised.

4c. The combination with a coupling-head having an opening in itsbottom, a knuckle having a tail provided with an inclined lower face, ofan operating device vertically movable through the opening in thebottom' of thecoupling-head, said operatingdevice cooperating by camaction with the knuckle-tail to I throw the knuckle open when saidoperating device is raised, and an antifriction device between the facesof the operating device and the knuckle-tail.

The combination with a coupling-head having an openingin its bottom,aknuckle having a tail provided with an inclined lower face,

and a locking-block, of .anoperating device constructed to embrace thecoupling-head and having a part vertically movable through the openingin the bottom of the coupling-head,
